A recessive allele will only lead to expression of a recessive trait in homozygous recessive individuals.What is a Recessive Trait? A recessive trait definition is one that is only expressed when an organism has two recessive alleles for that trait. A trait is an observable characteristic. This...
Recessive alleles are masked by dominant alleles. A person's genotype is the combination of the alleles they have. If a person inherits two dominant alleles, they are said to be homozygous dominant. If a person inherits two recessive alleles, they are said to be homozygous recessive. If a ...
This type of genotype may depict a higher fitness relative to either the homozygous recessive genotype or homozygous dominant genotype. This is referred to as a heterozygote advantage. Some examples of genotypes are – height, hair colour etc. Heterozygous phenotype The phenotype, in simple terms, ...
- Small b (b): When homozygous (bb), it results in reduced starch synthesis, leading to smaller starch grain size and a wrinkled seed shape. 4. Genotype and Phenotype Relationships: - BB (homozygous dominant): Produces large starch grains and round seeds. - bb (homozygous recessive): Pro...
What is the phenotype of a cross between homozygous dominant and homozygous recessive parents? When a parent who is heterozygous for a trait is crossed with a parent who is heterozygous for a trait, the offspring will (remember homozygous means two of the same alleles and heterozygous means two...
- If the genotype is homozygous recessive (bb), the starch grain size is small, and the seed shape is wrinkled. - In a heterozygous condition (Bb), the starch grain size may be intermediate, while the seed shape remains round due to the dominance of the allele for round seeds. 5. Con...
When you cross a homozygous recessive genotype with a homozygous dominant genotype, what is the expected phenotypic and genotypic ratio of the F1 generation? Consider a cross between a homozygous purple plant and a homozygous white plant. Suppose...
(a) What is the significance of the symbol of an element ? Explain with the help of an example. (b) Explain the significance of the symbolH. View Solution What is meant by 'convection' ? Explain with the help of an example. Why is it that convection cannot take place in solids ?
- The IO allele is recessive, meaning that it only expresses the O blood group when in a homozygous condition (IO/IO). 4. Co-dominance in Blood Groups: When an individual inherits one IA allele from one parent and one IB allele from the other parent (genotype IAIB), both alleles are...
selection of relevant SNPs, a search was conducted in the SNP database (https://www.snpedia.com/, accessed on 2 June 2017). The aim was to identify SNPs that were most commonly found in European populations, with a minimum occurrence of 1.00% for the minor genotype. Based on these ...
